PATENT WATER-WHEEL.

SPECIFICATION forming part of Letters Patent No. 644,94*?, dated March e, 190e.

Application tied november z2, 1899. serial No. 737,950. No model.)

To @ZZ L/hom) it may concert:

Be it known that I, WILH RONKAINEN, a subject of the Grand Duke of Finland, anda resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and Improved Vater-lVheel, of which the following is a full, clear, and exact description.

This invention relates to improvements in water-wheels; and the object is to provide a wheel of simple construction and comparatively light in weight that may be used in a small fall of water, and, further, to provide the wheel with an easily-operated cut-off and brake device.

I will describe a water-wheel embodying my invention, and then point out the novel features in the appended claims. i

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the iigures.

Figure 1 is a sectional elevation of a Waterwheel embodying my invention. sideview showing the position of parts when the Wheel is at rest, and Fig. 3 is a side view showing the position of parts when the wheel is in action.

Referring to the drawings, 1 designates a power-shaft on which is mounted a bandwheel 2, and secured to the power-shaft is the hub 3 of the water-wheel.` Secured to annular flanges on this hub 3 are arms 4 5, which extend outward and converge to a connection with a ring 6, and from this ring 6 the said arms diverge and then extend outward at right angles to the axis'ot the hub. Also connected to the ring 6, between the arms 4 5, are arms 7 and 8, which are shaped to correspond to the shape of the outer portions of the arms 4 and 5. These several arms, for the` sake of lightness with a sufficient degree of strength, I form of angle-iron yof L. shape in cross-section. The outer ends of the several arms are connected to rings 9 and 10, and connected to the outwardly-extending portions of opposite arms are the blades 11. The several arms may be braced between the ring 6 and the outer rings by intermediate rings 12.

Mounted to move circumferentially on the wheel is a cut-oft and brake device, consist-y ing of a boxing which has a portion to extend Ato the depth of the blades.

Fig. 2 is a across the periphery of the wheel and por'- tions to extend down the sides of the wheel Secured to the boxing are rollers 14, which extend through openings in the peripheral wall of the boxing and engage with the rings or tracks 9 and 10, as clearly illustrated inFig. 1. The boxing consists of two sections 13 and 15, hinged together at their adjacent ends. Attached to the section 13 ot' the boxing is a bracket 16, which extends from a hub 17 of a worm-wheel 1S, mounted to rotate loosely on the shaft 1, and engaging with this worm-wheel is a worm'- screw 19, mounted in a standard 20extended from the base 21.

A shaft 22 is mounted to rotate in a downwardly-extended arm of the bracket 16, and on this shaft is a pinion 26, which engages with the rack portion of a-bar 24, connected to the section 15 of the boxing. 'The rack portion of the bar 24 is held in engagement with the pinion by means of a pin 25, extended from the bracket 16.

As a means for quickly stopping or retarding the` motion of the wheel, as will be hereinafter described, I employ a series of dogs 26, pivoted in lugs extended from one side of the boxing and made in the form of anglelevers, the outwardly-extended portions of which are pivoted to a curved shifting rod 27, having a handle 28. These dogs project through openings in the peripheral wall of the boxing and are adapted to engage with teeth of a ring-shaped rack 29, which is. herev shown as attached to the blades 1l. At the side opposite that on which the bracket 16 is located the boxing is 'supported by an arm 30, which extends from the shaft 1 and has slots in its outer end through which pins on the boxing extend.

For operation the wheel is to be placed to receive the overflow from a dam or the like, which may be comparatively low. When it is desired to start the wheel, the worm-gearing is to be operated to move the boxing to the position indicated in Fig. 3. Then of course the fall ot' water by engaging with the blades will rotate the wheel. Should it be desired to retard the speed of the wheel, the

pinion 23 may be rotated by means of a handwheel 22a on its shaft 22, and this, by operat- IOO ing upon thc rod 24, will draw the section 15 caller?V of the boxing toward the wheel to cause the rollers 14 to engage more orless tightly against the outer rings or tracks. When it is desired to stop the Wheel entirely, the Worm mechanism is to be operated by turning the boxing into the position indicated in Fig. 2. This of course will deflect the water from the blades; but should the wheel be moved slightly by the current it may be effectually stopped by operating the bar 2l, .as before described.

Should it be desired to hold the wheel from rotating when the boxing is in the position indicated in Fig. 3, the rod 27 may be shifted to move the dogs 26 into engagement with the rack 29.

It is obvious that a wheel constructed as described may be made very light, yet strong and serviceable. Because of this lightness it may be easily transported from place to place When desired.

Having now described my invention, I claim as new and desire to secure by Letters Patenty l. A Water-wheel, a cut-off and brake consisting of a segmental boxing, means formoving the boxing circumferentially of the wheel, and means for causing a braking connection between the boxing and the wheel, substantially as specified.

2. A Water-wheel,comprising a shaft, arms extended outward from said shaft, blades mounted in the outer portions of said arms, a cut-oft` consisting of a segmental boxing, means for moving said cut-off circumferentially of the wheel, and means for drawing a portion of said boxing into tight engagement with the Wheel, substantially as specified.

3. A Water-wheel, comprising a shaft, arms extended outward from the shaft, blades secured on the outer portions of said arms, a cut-off and brake consisting of a boxing en gaging around a portion of the Wheel, rollers mounted on said boxing and engaging with peripheral bands or rings on the Wheel, means for causing movements of said boxing circumferentially ofthe wheel, and means for drawing one section of the boxing toward the wheel to cause the rollers mounted thereon to engage more or less tightly against the rings or bands of the wheel, substantially as specified.

4. A Water-wheel, comprising a shaft, arms extended outward from said shaft, blades secured on the outer portions of said arms, a segmental boxing engaging around a portion of said wheel, a Worm-wheel mounted on the shaft, a bracket connecting said Worm-Wheel with the boxing, a Worm-shaft engaging with the Worm-wheel, and means for causing the boxing to engage more or less tightly against the periphery of the Wheel, substantially as specified.

5. A water-wheel, comprising a shaft, arms extended outward from said shaft, blades secured on the outer portions of said arms, a cut-off consisting of a segmental boxing mounted on the wheel, rollers attached to said boxing and engaging with peripheral rings on the wheel, a worm mechanism for moving said boxing circum-ferentially of the wheel, a rack-bar having connection with the boxing, and a pinion engaging with said rack-bar for moving the boxing toward and from the Wheel, substantially as specified.

6. A water-Wheel, a segmental boxing movable circumferentially ofl the wheel, means for causing the movements of said boxing, dogs mounted on the boxing, a rack attached to the wheel and With which said dogs are adapted to engage, and a rod for moving the dogs into and out of engagement with the rack, substantially as specified.

7. The combination with a water-wheel, of a cut-off and brake consisting of a segmental boxing formed in two hinged sections, means for moving the boxing circnmferent-ially of the wheel, and means-for moving one of the sections toward and from t-he wheel, substantially as specified.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.

WILHO RONKAINEN.
